How to connect...
Before you start
with the electrical connection of the system, you must have done a correct installation of the delive-
red components. This installation must be done by an authorized and certified company/person.
Please be aware: an incorrect installation may destroy the DFM-System and damage your vehicle. In this case,
Aquametro will deny all responsibilities.

Please read the
Installation Tips
before you start.
1. With the DFM-BC in front of you, open the side-wings of the box and unscrew the 4 screws. Put the upper part of
the DFM-System careful a side. The upper part is connected to the base part with a flat cable.
2. Look at the print on the base. You will see a terminal block with 14 positions.
3. Take the cable from the DFM-8D and pass it through one of the glands of the DFM-BC. Tighten the gland-
nut very well by hand, until the cable is fixed.
4. Now connect the wires from the DFM-8D according to the table below to the terminal block on the DFM-BC print:

To ensure a proper function, the cable, described in the procedure below,
must be
connected directly to the vehic-
le’s battery. Do not connect it over the start-key of the vehicle. That means, also with the vehicle key in your pocket the
DFM-BC must be electrically powered. The power consumption is far below 1mA.
5. Connect a two wire cable (0.75 mm
2
) from the vehicle battery, through one of the gland of the DFM-BC, to the con-
nector position 13 (batt. plus) and position 14 (batt. minus). Tighten the gland-nut very well by hand, until the cable
is
fixed.
6. After all cables are connected and well in place, put the upper part of the DFM-BC back to the base part and screw
it
down.
7. Look at the type plate of the DFM-8D flow meter. Read the value for the SL-KF and the RL-KF (it must be a va-
lue
like
SL KF +0.12 or SL KF -0.13)
. Keep this value in mind or write it down to paper.
These values are needed to reach optimal performance.
8. Take the DFM-BC. If it is off, press one of the 4 Keys on the front to reactivate it.
Go to the menu point <Service>.
Press <OK> and enter the Service-Code. Standard service code is: 1111.
